To all whom it may concern.'

lle it known that we, Chaussee. ll. Now- .um and ll/uuiv M. lrmolca,citizens of the United States, residing at St. Louis, Missouri, have,invented a certain new and useful Improvement in Car-'l`ruek Frames` ofwhich the following is a full, clear and exact description, such as willenable others skilled in the nrt to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification, in which-f. v Figure I is a top dan view of atruck frame ol' our impl-oreal const ructiou. Fig. .2

is a plan view partly inhorizontal section of one side of n truck frameof our improved construction. Fig. it is a lsection taten the. linel2t2l of Fig. I. Fig. 4 is an enlarged cross section taken approximatelyon the. line l--4 of Fig. 1.

'l`his invention relates generally to cat' truck frames of the typewhich are cast or formed iu a single. piece, aml more part icularly tothe meansl for comici-ting the upper portions of the .swing hangers tothe truck frame.

'l`he ninci ml ob'ects of our invention are? to provide strong,substantial bearings for the up er ends of the swing hangers at the endsof the transoms of the truck, and to reinforce thel transomsadjacent tothe bearings for the swing hangers in order to'fully overcollie allstrains and stresses which may be g imparted to the truck frame by saidswing hangers while in service.

'l`o the above purposes our invention con- 1 sists in certain novelfeatures of construc-I tion and arrangement of parts hereinafter' morefully described and claimed.

ln the drawings we have illustrated a four-wheel cast metal truck framethe same eomprising the side or wheel pieces 1 and the transverselydisposed inner transoms 2 and outer transoms It. These transoms arepreferably ehanmlshaped in cross section,

euch comprising a vertically disposed web.y

the widened end portions 4 adjacent tlhe openings 5 are. verticallydisposed webs 6 which occupy iositionsparallel wlth the .i vertical websof the inner transoms 2, and lformed through these vertical webs 6 andilthe vertical webs of the inner transoms 2 immediately'above theopenings 5 are apertures 7 which are in horizontal alinement with oneanother. lf desired these aperj `tures 7 may bc provided with bushings8, although this construction is not absolutely essential. Uniting theupper portion of each web 6 with the adjacent vertical web of the innertransom is a horizontally disposed web t). 'lhe vertically disposed webtl and horizontally dis osed web f) combine. to form an 'inverterV L-shaed housing directly over the opening 5, w iich housin materiallystrengthens the vertical web an bottom flange of the transom, and thevertical web 0 provided with the opening 7 forms a bearing for one endof the pin or bolt I frolu which the swing hanger .f\ is suspelulill.

'l`he construction just described forms very strong. substantialbearings [or the upnu' ends of the swing hangers which, as lureinlaforestated, project through the openings- 5 and receive horizontallydisposed plus lt which extend thi-nigh openings formed in the upper endsof' said swing hangers and through the bushings in the opcniu1`-I T.'I'he webs tl are connected with the vertical webs of tho innertransouis bv the webs tt which extend horizontally with said transoms,thereby avoiding any crossed connectingmembersbetween tlu`iuljacentinnel and, outer transoms, which latter construction isdillicult to cast besides being liable to cause shrinkage cracks whichmaterially weaken eastin softhiseluuacter. 'l`he end portions of the)ottoln flanges of the inner transoms are widened in order to provide.ample strength for the trausoms at. the points where the swing hangersare suspended, and such widening makes up for the metal removed by theformation of the openings in said bottom flanges.

When in service car truck frames are subjected to strains (lue toconstant movement of the swing hangers lengthwise. of the truck, whichmovement causes corresponding movement. toall of the. swing hangermembers, and, as a result, the metal in the transoms of the truck frameis gradually fatigued, and to overcome this action the ends of the innertransoms are widened and extra wide gusset plates between the ends ofthe transoms and the wheel or side pieces of the frame are utilized,(hereby bringing both transoms into action at the same time to resistthee-:trains due to the. lmekward and toni (langes ada te to receive thcu iper ends of swing iangers. and inverted l..- shiiped reinforcingmembers iiitegral with sau l ings. i 2.
